T0 :f1/Z whom t may concern:

Be it known that I, MYRON Gr. BROWNELL, a citizen of the United States of America, residing in the city and county of Denver, State of Colorado, have invented certain new and useful Improvements in Telephone-Directories; and I do declare the following to be a full, clear, and exact description. of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciication.

y invention relates to improvements in what I term a telephone-directory, being a device adapted to be mounted on the telephone between the mouthpiece and transmitter, and therefore readily detachable. It may either be loosely clamped between the mouthpiece and the transmitter or simply hung upon the mouthpiece in such a manner that in either event it may be easily turned in order to bring any desired name into proper position for observing the corresponding phone-number. It is therefore revolubly mounted, and its body portion is provided with interior and exterior circular flanges in which are inserted theinner and outer extremities, respectively, ofl sections or parts of suitable size to contain the name and number of a telephone subscriber.

My improved device is of circular shape, and it is of a size adapted to contain a name section or piece for those subscribers which any individual in the course of his business converses frequently with over the phone.

The device is also believed to be important as a collector of sound-vibrations. It is found in practice that where this device is used it is possible to converse in a lower tone of voice than where it is not employed.

Having briefly outlined my improved construction, as well as the function it is intended to perform, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is a face view of my improved device mounted on a telephone,

the mouthpiece only of the telephone being visible. Fig. Q is a side elevation ofthe same. Fig. 3 is a sectional detail view of the device shown flat. Fig. 4 is a similar view showing the concave-convex form. Fig.v 5 is a detail view of one of the name sections or pieces forming a part of my improved device.

The same' reference characters indicate the same parts in all the views.

Referring first to Figs. l, 2, and 3, let A designate myimproved device, which is circular in shape and may be formed from a thin piece of material constituting a disk A, having a flange A2, inwardly turned at its outer edge and a similar flange A3, outwardly turned at its inner edge, surrounding the central opening Ai, throughy which the mouthpiece B of thetelephone passes. In the grooves or ways formed by the fianges A2 and A3 are inserted the extremities of sector-shaped name sections or pieces O, each adapted to contain the name and corresponding number of a telephone subscriber. These pieces are preferably cut sector shape in order that they may iit nicely into the circular space between the two circular flanges A2 and A3. It is evident that this directory will possess sufcient capacity to contain all of the subscribers with whom the ordinary individual is accustomed to frequently converse through the agency of the telephone. These names, itis evident, maybe arranged in alphabetical order, and any name section or piece may be readily removed and another section containing another name and number as readily inserted. It is preferred that the name-sections shall consist of paper sufficiently flexible so that by bending the piece slightly in the middle its extremities may be inserted in or detached from the body of the directory, as may be desired.

In applying the device toa directory the mouthpiece is first unscrewed from the receiver, after which the mouthpiece is inserted through the opening Al of the device and screwed into place again. If desired, the device may be loosely clamped between the shoulder of the mouthpiece and the receiver, or the device may simply hang loosely on the mouthpiece.' This last mode of attachment is believed preferable, since there is no necessity IOO that the device shallbe attached with any special degree ol' security or rigidity, while it is important that it should be allowed to turn freely on the mouthpiece, and it is thought this can best be subserved by having it loosely hung on the mouthpiece independently of the clamping feature, though it must be understood that I do not limit myself to any special method or means ot' attachment.

In the form of construction shown in Fig. 4 the disk is Jformed concavo-convex, its face or front surface being concave. This form of the device is designated A5. In other respects it is exactly the same, having the flanges A2 and A3, adapted to hold the name sections or pieces C. rIhis form of the device may under some circumstances be preferable. It will be understood, however, that the disk may be either flat or concavo-convex, also that the degree of concavity may be regulated as may be desired. As shown in the drawings, I) designates the telephone-transmitter, and E the standard upon which it is pivotally mounted, as shown at F.

In Fig. 4 the name-pieces are shown in elevation. Attention is called to the fact that the name-pieces of the directory may be moved around the disk Without detaching them, the movement being simply a sliding action, as their extremities will move readily in the grooves or ways formed by the flanges A2 and A3.

Having thus described my invention, what I claim is- 1. A telephonedirectory, consisting of a disk adapted to be revolubly mounted on a phone, and having interior and exterior anges, and name pieces or sections whose extremities are adapted to enter said `llamges whereby the said pieces are retained in place.

2. The combination with a telephone, of a device consisting or' a disk having a central opening through which the mouthpiece passes, the disk being revoluble on the phone and having interior and exterior flanges turned toward each other whereby circular grooves or ways are formed, and name sections or pieces whose inner and outer extremities are adapted to respectively enter said grooves or ways.

3. A telephone-directory comprising a disk having a central opening and flanges formed around said opening and around the exterior periphery of the disk, the said llanges being turned toward each other and forming grooves or ways, and i'lexible name-pieces whose extremities engage the said grooves or ways of the disk, and are so arranged that by bending the piece between its extremities, it may be attached to or detached from the disk.

4. A telephone-directory comprising a disk having a central opening and provided with interior and exterior flanges turned toward each other to forni grooves or ways, and sectorshaped name-pieces whose extremities engage the said grooves or ways, the said pieces being' arranged to collectively constitute an area equal to the area ot' the disk.

In testimony whereof I alix my signature in presence of two witnesses.
